Convert rgb/rgba color value to hex code

Hi Folks,

Steps I followed:

1. Drag the text block.
2. set the font color. (its in rgb/rgba format)

What I Expected: Style needs to be updated as like hexa code. (like, #f0f0f0)

I tried to get the particular color update using, editor.on('component:styleUpdate:color', function (model) { . But I could not get the solution. Guide me how to achieve the expected solution.

Thanks in advance, Prabha.
